what is the weight of each cat? (c++ code for this problem)
Kion has three cats. Each has different weight. The 1st & 2nd weigh 9kg altogether. The 2nd & 3rd weigh 10kg altogether. The 1st & 3rd weigh 13kg altogether. What is the weight of each cat?

Hey, Jobelle you can use this code also with same sequence like your question. Here it is
#include <iostream>
using namespace std;
int main() {
int a,b,c,x,y,z;
cout << "Please enter constant of three equcations\n";
cin >> a >> b >> c;
cout << "You have entered\n" << "x+y=" << a << "\ny+z=" << b << "\nx+z=" << c << endl;
x=(2*a-(a-c)-b)/2;
y=((a-c)+b)/2;
z=(2*b-(a-c)-b)/2;
cout << "Weight of 1st cat: " << x << "\nWeight of 2nd cat: " << y << "\nWeight of 3rd: " << z;
return 0;
}

Here, it is
#include <iostream>
using namespace std;
int main() {
int a,b,c,x,y,z;
cout << "Please enter constant of three equcations\n";
cin >> a >> b >> c;
cout << "You have entered\n" << "x+y=" << a << "\ny+z=" << b << "\nx+z=" << c << endl;
x=(2*a-(a-b)-c)/2;
z=(2*c-(a-b)-c)/2;
y=((a-b)+c)/2;
cout << "Weight of 1st cat: " << x << "\nWeight of 2nd cat: " << y << "\nWeight of 3rd: " << z;
return 0;
}
I have use simple algebra method. But If you want I can show you in other also. Here input sequence is matter. I have assume 1st cat as x, y as 2nd cat and z as 3rd one. I am talking about weight.
so, enter your data as
x+y=9
x+z=13
y+z=10
+ 2
1st cat - 6
2nd cat - 3
3rd cat - 7
And I am going to write code.

Only for this one, if it x,y or z has a co-efficient then No

how are you prople able to build an algorithm so easily?
x+y=9 nd y+z=10 nd x+z=13
other than those above codes i cant get any more further steps😢

@Aditya Kumar pandey will it work for any linear equation with three unknowns ?? or it for this problem specifically
